U.S. Cl. 131-202 3 Claims ABSTRACI` OF THE DISCLOSURE A smoking pipeincluding a bowl, a mouthpiece and a tubular stern extensiontherebetween. Within the extension there is an inner tube or ductconnected with the bowl, around the duct and spaced therefrom there is atube having a closed end and around the tube there is a filter. Fillingthe space between the filter and the inner surface of the stem extensionthere is a layer of absorbent material for absorbing any saliva enteringthe pipe through the mouthpiece. A feature of the invention has to dowith fingers on the filter making contact with the absorbent material soas to transfer moisture from the fingers to the absorbent material.

This invention relates to smoking pipes and has reference to a combinedfilter and moisture absorbent for reducing the amount of so called tarsfrom reaching the mouth and for preventing moisture from reaching thetobacco in the pipe bowl. Additionally, the path of the smoke is greaterthan the length of the pipe, thereby cooling the smoke before reachingthe mouth. The path of the smoke also includes a moisture trap forfurther preventing moisture in the mouthpiece from reaching the bowl andthe tobacco therein.

`One object is to provide a smoking pipe which does not go out readilybecause moisture from the mouthpiece does not reach the bowl.

Another object is to provide a pipe having an absorbent and filter, bothof which are easily replaced.

These and other objects of the invention will Ibecome apparent from thefollowing description and the accompanying drawing, in which:

FIGURE 1 is a longitudinal sectional view of a smoking pipe according tothe invention.

FIGURE 2 is an enlarged perspective view, shown partly in section, ofthe bowl fitting, mouthpiece, stem extension and parts containedtherein.

FIGURE 3 is a side elevational view of the moisture absorbent.

FIGURE 4 is an enlarged end view of the absorbent, filter and the closedend of the tube.

FIGURE 5 is a fragmentary perspective view of a preferred filterconstruction in sheet form before rolling lengthwise, and

FIGURE -6 is an enlarged broken longitudinal sectional view showing theoutlet end of the duct, the closed end of the tube and the filtertherearound.

The pipe shown in the drawing includes a bowl 10, a mouthpiece 11 and atubular stem extension 12 therebetween. The mouthpiece 11 is attached tothe stern extension 12 by threads 13, whereas the remaining end of theextension is attached to the stern 14 of the bowl by a fitting 15. Asbest shown in FIGURE 2, the fitting 15 is comprised of forward threads16 which engage the bowl 10, rear threads 17 which engage the stemextension 12 and a fiange 18 therebetween. There is an 'ice axialopening 19, and pressed into the opening there is a rearwardly extendingtubular duct 20. The duct 20 extends nearly the length of the sternextension 12 and is open at both ends. However, there are lateralopenings 21 near the rear end of the duct 20 to facilitate the flow ofsmoke. Around and spaced from the duct 20, and extending rearwardlythereof, there is a tube 22 having a closed rear end 23. The forward endof the tube 22 is spaced rearwardly from the fitting 15 to provide alateral passage 24 which is best shown in FIGURE 2 (see also FIGURE 1).Within the scope of the invention any suitable filter may be providedaround the tube 22, but a preferred filter 25 is comprised of a lengthof paper 26 having punched vertically extending fingers 27. The lengthof paper 26 is wrapped, lengthwise, around and may be bonded to the tube22 by means of a suitable adhesive with the fingers 27 projectingoutwardly. Within the stem extension 12, and extending between thefitting 15 and the mouthpiece 11, there is a tubular absorbent 28, theouter diameter of which is in contact with the inner surface of theextension and the inside diameter contacts the outer ends of the filterfingers 27. The absorbent may be made of various materials, for example,paper towels, cotton batting, wood pith, etc. Glue (not shown) on theends of the fingers 27 may be used to secure the absorbent 28 to thefilter 25. There is a longitudinal groove 29 in the bottom inner surfaceof the mouthpiece to direct liquid in the latter to the absorbent 28.

In operation, tobacco is placed in the bowl 10 in the usual manner andlighted while drawing on the mouthpiece 11. Smoke travels from the bowl10, through the opening 19 in the fitting 15, and out through the end ofthe duct 20. By reason of the closed end 23 on the tube 22, the smokethen travels forward through the tube, through the lateral passage 24,rearwardly through the filter 25 and thence out through the mouthpiece11. The tortuous path of the smoke cools the same and at the same timethe filter 25 and contact with the absorbent 28 removes a substantialamount of the so called tars and other extraneous matter. Since an endof the absorbent 28 is in direct contact with the mouthpiece 1'1,accumulated saliva is readily absorbed. Additionally, any excessmoisture in the absorbent 28 cannot reach the bowl because the describedarrangement of the tube 22 and duct 20 serves as a moisture t-rap.

The invention is not limited to the exemplary construction herein shownand described, but may be made in various ways.

What is claimed is:

1. In a smoking pipe including a bowl, a mouthpiece and a stem extensionconnected therebetween, means providing a duct in communication withsaid bowl and extending rearwardly therefrom into said stem extension, atube around and spaced from said duct, a closure on the rear end of saidtube, lateral passage means at the forward end of said tube, passagemeans around said tube communicating said lateral passage means withsaid mouthpiece, a tubular absorbent within said stem extension and afilter around said tube and in contact with the inner surface of saidtubular absorbent.

2. In a smoking pipe as defined in claim 1, the construction whereinsaid filter is comprised of a tube having lateral fingers extending toand in contact with said tubular absorbent.

3. In a smoking pipe as defined in claim 1 and including means providinga longitudinal internal groove in the bottom inner surface of saidmouthpiece and in communcation with said tubular absorbent.
